The Accutech SI10 wireless switch input field unit is ideal for determining the state of contact switches without running wiring in the field. Two switch contacts operate with a debounce filter or as a counter by counting contact state changes up to 5Hz. Two optional switch outputs* may be added for switching external power sources up to 1A at 30V.
All Accutech field units automatically report field data to a centralised Accutech base radio over distances of up to 3000ft (~1000m). Each field unit is self contained, featuring an integrated 900MHz or 869MHz (license-free band), frequency hopping, spread-spectrum transceiver and antenna, and longlasting battery that offers 3+ years of maintenance-free service (up to 10 years depending on data rates and battery options). Accutech networks are highly scalable with the possibility of 100 field units per base radio and 256 base radios per installation. Accutech field units are housed within a compact and weather-proof NEMA 4 enclosure with options for a remote sensor and remote antenna on select models. Field units are available in a wide range of certifications and are protected by an industry leading 3-Year warranty (parts and labor).
